Acts 20:29-31

Revised Standard Version Catholic Edition

²⁹ I know that after my departure fierce wolves will come in among you, not sparing the flock; ³⁰ and from among your own selves will arise men speaking perverse things, to draw away the disciples after them. ³¹ Therefore be alert, remembering that for three years I did not cease night or day to admonish every one with tears.
